Study On The Effect Of Various Levels Of Dietary Protein In Quail - 1985

The experiment was conducted on 270 one day old Japanese quail (Coturnix Coturnix Japonica) to study the effect of various levels of dietary protein on the performance of quail chicks. The chicks were randomly divided into five experimental groups, comprising 54 chicks. Each group was further sub-divided into 3 replicates of 18 chicks each. The data collected was statiscally analysed using analysis of variance.
Five experimental rations A, B, C, D and E containing 24, 26, 28, 30 and 32 percent protein were prepared respectively. The rations were isocaloric, each containing about me 2800 Kcal/kg. The allotted rations and fresh water were provided to the respective groups ad lib for a period of eight weeks. Brooder temperature was maintained at 95o F during first week of the study. It was lowered at the rate of 5oF every week till it reached 70oF, thereafter it was kept constant. The rest of the managemental and environmental conditions were identical.
The results of the study revealed non-significant difference in body weight, feed consumption and feed conversion in all the five groups of experimental chicks. Best feed conversion ratio was observed in chicks fed on ration B and C containing 26 and 28% protein respectively. Chicks fed on ration A, D and E revealed poor feed conversion ratio. Maximum mortality (7.4%) was observed in chicks fed on ration B containing 26% protein.
The results indicated that birds fed on 26% protein gave the highest dressing percentage (70.2) while chicks fed on 24% protein gave the minimum dressing percentage (65.1). Best feathering was observed in group B fed on ration containing 26% protein and poorest feathering was in the chicks fed on ration a containing 24% protein.
Results of the experiment indicated that chicks fed on 26% protein ration gave the best performance and were quite economical.
At the end of study, it was found that Japanese quail (Coturnix Coturnix Japonica) can be reared economically on a ration containing 26% protein under local environmental conditions with best weight gain, feed conversion ratio, feather development, dressing percentage and lowest mortality percentage.
It is, therefore, recommended that the quail should be reared by using 26% protein in ration.
